Well, we shall make it a penalty, in fact the
maximum imposable by the state, to interfere in any way with a persons open, public, commons vote or .. data .. related to that action, in any way.
You enter the booth, the light goes on, anything you want to say will be recorded for posterity by the state, for the public sphere, and you state who you support. Its an open public record, and therefore also the right place to let the government know that you are under duress and need assistance with exercising your right to vote.
So it goes more like, "I'm Jimmy, and I'm being forced to vote for Madam X, I want my government to address this grievance", and so it does.
I mean, the point of this theoretical is to realize that we have the mafia shit-storm we have right now, because things are secret.
That secret veil, once removed and turned instead into 15-minutes of fame for everyone, because its your right to do so, means you're gonna have a lot more people interested in voting, buddy.
No matter how many chumps Madam X has on the payroll.
